Design Principle 1: Simplicity favors regularity
→ use register operand(피연산자)
Unlike programs in high-level languages, the operands of arithmetic instructions are restricted; they must be from a limited number of special locations built directly in hardware called registers.
what is register?
special location built directly in processor = much faster access compared to main memory
